Answer :
Lines p and r are parallel!
Explanation:
The angle formed at the intersection of line n and line p is measured as 130. The other angle downwards of angle 130 measures 50, because angles on a straight line equals 180. That is;
130 + x = 180
x = 180 - 130
x = 50
Angle x (50) is corresponding to the one at line r, since they're both formed at the same point on both line segments.
Corresponding angles are equal.
That makes line p and line r to be parallel.
